A handheld game controller for use with a dedicated game system, personal computer, or other device is provided. The game controller includes two user grippable portions, typically a pair of handles, which the user holds during game play. As a result of this configuration, during use the game controller neither rests on nor becomes attached to a rigid surface such as a desk, tabletop, or other stationary object. In one aspect, one handle of the game controller is held by one of the user's hands while the second handle of the game controller, held by the user's other hand, is free to rotate within the predetermined rotational limits of the device. In a typical application, right direction and left direction control signals are sent to the game system or personal computer as a result of clockwise rotation and counter-clockwise rotation of the second handle of the game controller, respectively. A sensor coupled to the second handle generates the control signals. A tensioning system is preferably used to urge the second handle of the game controller to a null position typically located halfway between the extreme clockwise and counter-clockwise positions of the second handle.
